Marigolds (Calendula)

Marigolds are beautiful flowers that come in various shades of yellow, orange, and red. They are incredibly easy to grow from seeds and will continue to bloom throughout the entire summer. These flowers can reach a height of up to three feet, adding a lovely touch to any garden. When planting marigolds, make sure to space them about 15 cm apart. You'll be delighted to know that each plant can produce up to 5 stems simultaneously, making them an ideal choice for creating vibrant cut flower arrangements. The best part is that marigolds have a cut and come again characteristic, meaning the more you pick them, the more flowers they will produce for you to enjoy.
Cosmos
Cosmos is a delicate flower with daisy-like petals that come in various shades, including pink, white, red, and recently, peachy tones. It blooms during the late summer and early autumn, adding vibrant colors to your garden. These flowers can grow up to four feet tall and wide, creating a stunning display. When planting Cosmos, make sure to space them 20 cm apart to give each plant enough room to thrive. Each plant can produce up to 10 stems, providing an abundance of flowers. Not only are these flowers a delight to look at, but they also attract butterflies, adding even more life to your garden. Additionally, Cosmos flowers make excellent cut flowers, and the more you pick, the more flowers they will produce, allowing you to enjoy their beauty both indoors and outdoors.

Gomphrena

Gomphrena is a stunning globe-shaped flower available in lovely shades of pink, purple, and white. It flowers during the summer season and can reach a height of up to two feet.

One interesting fact about Gomphrena is that each plant can produce up to 3 stems, making it an excellent choice for adding a unique touch to cut flower arrangements. When using Gomphrena as cut flowers, it is best to cut them when they are in bloom but not fully open. On the other hand, if you want to create dried, everlasting flowers, wait until they are fully open and then hang them upside down to dry.
Larkspur
Larkspur is a beautiful flower that comes in shades of blue, pink, and white. It belongs to the delphinium family and is the annual variety. It blooms during the summer, reaching heights of up to four feet. When planting Larkspur, make sure to space the plants 20 cm apart. Each plant can produce one stem at a time, but once you pick the flowers, more will grow. This is perfect for creating tall and structured cut flower arrangements. It's important to note that Larkspur doesn't like its roots to be disturbed, so it's best to directly sow the seeds in April and provide some protection during frosty nights. Germinating these seeds can be a bit challenging, but with a little perseverance, you'll achieve great results that are definitely worth it.

Malope

Malope is such a stunning flower! It has these lovely large petals that come in such beautiful shades of pink, red, and white. The best part is that it blooms from mid-summer to fall, so you can enjoy its beauty for a long time. And guess what? It can even grow up to three feet tall!
